Fuel is supplied to the surge tank by a lift pump, which in most cases is the OEM in-tank fuel pump.  The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel, even if the lift pump starves momentarily.\u003c\/p\u003e\n\n\u003cp\u003eThis volume is maintained by the lift pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgade any standard fuel system without opening the stock fuel tank. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.

Multiple high flowing fuel pumps can be used in the surge tank.\u003c\/p\u003e\n\n\u003cp\u003eNEW FEATURES\u003cbr\u003e\nIn addition to all previous MPFST features, the new MPFST rendition is packed with innovations.\u003cbr\u003e\n-Up to 3 Bosch BR540 fuel pumps (DW400) \u003cbr\u003e\n-Up to 2 Ti Automotive E5LM brushless pumps\u003cbr\u003e\n-Up to 3 brushless Bosch pumps (DW440)\u003cbr\u003e\n-Anti-rotation electrical terminals\u003c\/p\u003e\n\n\u003cp\u003eThe outlet from the fuel pumps merge into a single outlet simplifying external plumbing. And because the compatible pumps utilize check valves, staging is permitted. NOTE: The brushless Ti Automotive E5LM MPFST includes check valves (shown below in green).\u003c\/p\u003e\n\n\u003cp\u003eThe brushless Ti Automotive E5LM MPFST pump outlet merge collector shown below.\u003c\/p\u003e\n\n\u003cp\u003eThis \"FUEL PUMP OUTLET\" port is 10AN ORB threaded but comes preinstalled with a -8AN male adapter fitting. The \"OVERFLOW\", \"SUPPLY\", and \"RETURN\" ports are all 8AN ORB threaded but come preinstalled with -6AN male adapter fittings. All of these fittings can be swapped out with different sizes (sold separately).\u003c\/p\u003e\n\n\u003cp\u003eWhen fuel enters the MPFST through the \"SUPPLY\" and \"RETURN\" ports, it gets redirected and runs tangential through the canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance.\u003c\/p\u003e \n\n\u003cp\u003eThe pumps are mounted using an anodized aluminum bracket. All internal wires are gasoline, ethanol, and methanol compliant. The brushless Ti Automotive E5LM MPFST (shown above) utilizes a standard press-in filter sock included commonly with the pump (or HERE).\u003c\/p\u003e\n\n\u003cp\u003eAll other pumps use the provided stainless steel mesh inlet screen for pre pump filtration shown above. As depicted below, fuel cannot pass between the 3 independent filtration chambers (A, B, C). NOTE: If less than 3 pumps are installed, the empty port does NOT need to blocked off.\u003c\/p\u003e\n\n\u003cp\u003eThe pump power connections are handled with specially designed high-current electrical studs. Necessary ring terminals and hardware are included with every surge tank.\u003c\/p\u003e\n\n\u003cp\u003eAs shown, the underside of the MPFST is suitable for uneven surfaces commonly found in the trunk of a vehicle.\u003c\/p\u003e \n\n\u003cp\u003eStainless steel M6x1.0mm socket head bolts are included for custom mounting.\u003c\/p\u003e\n\n\n\u003cp\u003e20-1440 MPFST, PUMPS NOT INCLUDED, WALBRO GSS342 OR AEM 50-1200 OR DW440\u003cbr\u003e\nThis MPFST comes ready for the end user to install 1, 2, or 3 pumps.\u003c\/p\u003e\n\n\u003cp\u003ePUMP COMPATIBILITY\u003cbr\u003e\nWalbro GSS342\u003cbr\u003e\nAEM 50-1200\u003cbr\u003e\nDeatschwerks DW440\u003cbr\u003e\nNOTES:\u003cbr\u003e\n1.
